In 1991, a partial cranium of a fossil colobine monkey was found in Kanagawa Prefecture, Japan. Its geological age is Late Pliocene (ca. 2.5 Ma). It is larger than skulls of living colobine monkeys and resembles a male example of Pliocene Dolichopithecus ruscinensis from France. However, the cranium exhibits some distinctive features, notably very thin postorbital rims (lateral margins of the orbit). Therefore, a new subgeneric and specific name Dolichopithecus (Kanagawapithecus) leptopostorbitalis is given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
